Alpha Lactalbumin IgG
Use
Alpha lactalbumin IgG testing is primarily used to assess immune response related to alpha lactalbumin, a major protein found in human milk and cow's milk. This test is used to identify and quantify allergen-specific IgG antibodies, which can aid in understanding patient's hypersensitivity or immune response related to dietary exposure to alpha lactalbumin.
Special Instructions
Ensure that the serum samples are collected and handled properly to avoid clotting. It is necessary to aliquot the serum into a plastic vial after centrifuging. The preferred shipping condition is refrigerated to maintain sample stability.
Limitations
Alpha lactalbumin IgG levels are not standardized to diagnose allergies or clinical conditions. Interpretation of results should consider clinical history and other diagnostic information. Sensitivity and specificity may vary, and the absence of antibodies does not necessarily rule out the presence of an allergy. This test has not been reviewed by the FDA and should not be used as the sole diagnostic tool for clinical decision making.
